THOMAS QUINN, OF FORT COLLINS, COLOR/A130.

DEVICE FOR SUPPORTING AND FASTENING SLIDING DOORS.

Specification of Letters Patent.

Patented Apr. 8, 1213.

Application filed July 13, 1911. Serial No. 638,276.

To all whom it may concern Be it known that I, THOMAS QUINN, a citizenof the United States, residing at Fort Collins, in the county of Larimerand State of Colorado, have invented certain new and useful Improvementsin Devices for Supporting and Fastening Sliding Doors, of which thefollowing is a specification.

The object of this invention is to provide an improved means forsupporting and fastening sliding doors, the invention being particularlyapplicable for use upon the sliding doors of railway freight cars.

In the accompanying drawings, Figure 1 is a fragmentary side elevationof a railway freight car equipped with a door hanger embodying thefeatures of my invention. Fig. 2 is a fragmentary view of one of thelower corners of the door showing one of the supporting brackets and therail par tially in section. Fig. 3 is a vertical section in the plane ofline 3-8 of Fig. 2. Fig. 4 is a horizontal sectional detail on line 44Fig. 2.

The body of the car is indicated at 5 and the door 6 is mounted to moveedgewise along the side of the body. The upper edge 'of the door isguided by a rail 7 of suitable form, being herein shown in the shape ofa Z-bar extending above the doorway of the car and to one side of saiddoorway substantially the width of the car door. The door is supportedat its lower edge on a Z- bar 8 extending below the doorwa said Z- barbeing secured to the side of t e car, in this instance by means ofbrackets 9.

At each of the lower corners of the door 6 is mounted a bracket 10comprising a portion 11 adapted to lie beneath the edge of the door, aflange 12 lying along the face thereof and a flange 18 contacting theedge of the door. Bolts 14: passing through the side flange 12 serve tosecure the brackets to the door. In the lower portion 11 of the bracketis formed an elongated recess or downwardly opening housing 15 in whicha roller 16 is adapted to travel, said roller running upon thehorizontal web of the Z- rail 8. In the present instance, the rollerruns loosely in said recess and is not provided with any journals. Therecesses 15 in the brackets 10 are of such length that during theopening of the door the rollers 16 will reach the end of said recessesbefore the door is fully opened, so that the dragging of the rollersupon the further opening movement of the door will effect a brakingaction thereupon to retard its movement and thus prevent the door fromstriking the stop 17 with too great force.

A wedge member 18 is pivoted upon a suitable bolt 19 extending throughthe car door and the bracket 10, the lower edge of the wedge memberbeing arranged to lie between the outer face of the bracket flange 12and the upstanding outer flange of the Z-rail 8. The adjacent faces ofthe bracket flange 12 and the wedge member 18 are provided with wedgingsurfaces 20 and 21 respectively. The member 18 thus serves to hold thedoor against the car and prevent rattling of the door. The wedgingsurfaces 20 and 21 are so formed that should the door become unlockedand tend to open due to the movement of the car, the member 18 would bewedged still more tightly between the bracket 10 and the Z-bar so as topositively prevent the opening of the door. When it is desired to openthe door the wedge mem ber 18 is swung upwardly to lie in the positionindicated in dotted lines in Fig. 2, when the door may be freely movedin its guideways.

18 is a lug on the wedging member providing a finger-hold for moving itand also serving as a stop to limit movement of said member when it isswung up into its inoperative position.

It will be noted that the portion 13 of the bracket extends along theadjacent side edge of the door and thus protects said edge againstinjury from the use of an implement which is sometimes used in openingor closing car doors. The rail brackets 9 add strength and rigidity tothe lower supporting rail 8.

It should be understood that the foregoing detailed description has beengiven for the sake of clearness only, and not with an intention to limitthe invention to the exact construction disclosed.

I claim as my invention:

1. The combination of a car door; a guide rail; brackets secured to thelower portion of the door; rollers mounted in said brackets and runningupon said rail; and a wedging member attached to one of said bracketsand adapted to be interposed between said rail and the door.

2. The combination of a car door, a Z-rail arranged to be attached tothe car below the member and said bracket having coacting 1b doorwaythereof, a pair of brackets secured wedging surfaces thereon.
